Mouse nerve growth factor for injection can promote the recovery of nerve injury, so can it be used to treat acute cerebral infarction? Mouse nerve growth factor for injection is a cell growth factor isolated and purified from mouse submandibular gland, and it is a bioactive protein. Mouse nerve growth factor has the dual functions of neurotrophic factor and neurite growth promoting factor, and plays a regulatory role in the growth, differentiation and regeneration of nerve cells. Exogenous nerve growth factor can protect sensory neurons and sympathetic neurons, reduce the degree of injury, promote the growth of regenerated nerve fibers, and is conducive to the recovery of nerve function. Therefore, nerve growth factor has a protective effect on neurons after central nervous system injury, which can prevent neurons from atrophy and death caused by injury and promote the recovery of nerve function after central nervous system injury. Rat nerve growth factor for injection has a good effect on the rehabilitation of nerve function, and has the functions of protection and repair. Rat nerve growth factor (NGF) plays an important role in protecting neurons by regulating calcium balance and resisting free radicals, especially in the process of secondary brain injury caused by cerebral ischemia. Studies have shown that for the central nervous system injury caused by various reasons (such as injury, infection, ischemia, etc.), timely supplementation of exogenous rat nerve growth factor for injection in acute stage can alleviate the injury of nerve cells, improve muscle tension, improve motor function, and promote the improvement of patients' quality of life, which has obvious rehabilitation effect. In addition, most scholars believe that injection of rat nerve growth factor can maintain the survival of neurons to avoid serious neuronal necrosis, accelerate the compensation process of normal neurons and neurons that do not work under normal conditions, and accelerate the recovery speed to achieve the purpose of treatment. Therefore, the injection of rat nerve growth factors (such as Enjingfu and Sutaisheng) has a certain short-term effect on acute cerebrovascular diseases such as acute cerebral infarction, and it has no serious toxic and side effects, and its clinical application is safe, and it can promote the growth and repair of the central nervous system to a certain extent, so it is worth using.
